A married couple lived aboard their boat at a local yachtclub's dock.

They planned to attend the Halloween costume party in the clubhouse at
the head of pier, but on the night of the event the wife came down
with a migraine and she urged her husband to go to the party without
her. He relucantly put on his very distinctive costume, (a full body
gorilla suit), gave her a kiss and set off to celebrate Halloween.

About an hour later, the wife realized that her migraine had subsided
and she decided to join the party. As she was getting dressed, she
made a last minute decision to change costumes, and instead of
attending as the ballet dancer she had originally intended she threw
together some old black clothes, dredged a scary face mask up from the
bottom of a locker, and went dressed up as a witch.

"This will be my chance to see how my husband behaves when I'm not
around!" she thought. "Not only does he think I'm back on the boat
with a migraine, he expects me to be dressed as a ballet dancer if I
do show up He won't recognize me as a witch!"

When the wife arrived at the party, it was in full swing. The wife
looked through the crowd to find her husband, and was very distressed
when noticed one couple making quite the display on the dance floor.
The "gorilla" was dancing way too closely with a shapely young woman,
blatantly massaging her butt with his hands, and she was rather
obviously encouraging and enjoying it.

"That *******!" said the wife. "I'll show him- since after all he
doesn't recognize me!"

The wife "cut in" at the next dance, and during the course of the
evening the "witch" made every suggestive move she could imagine- and
all were reciprocated by the "gorilla". After a few groping dances and
a couple of drinks, they found themselves sitting at a corner table,
and before long they actually had their hands inside one another's
costumes.

"It's OK for me," thought the wife. "I know this is my own husband.
But I can hardly wait to confront him about this as he thinks I'm a
total stranger!"

The witch excused herself to go to the restroom, but continued out the
door
of the club and ran crying all the way back to the boat.

About two hours later, her husband returned from the party.

"How was the party?" she asked, trying hard to conceal her sarcasm.
"Did you get a chance to dance with anybody?"

"No, I figured it was going to be pretty boring without you there, so
I went into the back room and played poker with three other guys for
the entire time."

The wife was heartbroken, not only had she caught her husband heavily
flirting with other women, but now he had the audacity to lie and
claim he was playing poker!

"I'll bet that was uncomfortable for you," she sneered, "Sitting there
playing poker for hours in that gorilla suit."

"Oh, heck no," responded her husband. "I figured I wouldn't need the
costume for playing poker, so I loaned it to your brother!"
